Gallop Road and Bridge Engineering Co., Ltd. Hengshui plate rubber expansion joints to welcome you to call us and discuss Gallop rubber expansion joints rubber shear plate is the use of low amounts of principles designed and manufactured by the shear deformation of the rubber to accommodate retractable deck displacement, and the horizontal (tension and compression) reaction force is small, favorable bridge structure. This product is made from steel skeleton, sub assembly, bolt connection, install, reliable, will not fall off, seams smooth, balanced driving comfort. When the product is installed, a bottom bolt holes and joints per meter are filling adhesive coated, waterproof good. This product is anti-aging, wear rubber processing, can withstand repeated loads of vehicles, long service life. Change, they are available when the new bridge construction. Product Specifications: Model Size (mm) (L × W × performance indicators: Technical indicators Neoprene (applicable and -25 ℃ ~ 60 ℃) natural rubber (for the -40 ℃ ~ 60 ℃) Hardness (IRHD) 60 ± 5 60 ± 5 Tensile strength (MPa) ≥17 ≥18 Elongation at break (%) ≥400 ≥450 brittleness temperature (℃) ≤-40 ≤-50 constant compression set (70 ℃ × 24h) (%) ≤15 ≤30 resistance to ozone aging (test conditions, 20% elongation, 40 ℃ × 96h) 100pphm 25pphm no cracks no cracks hot air aging test (compared to non-occurrence of the maximum value before aging changes) test conditions (℃ × h) 100 × 70 70 × 168 Tensile strength (%) ?? -15-15 Elongation at break (%) -40-20 change in hardness (IRHD) 0, + 10 -5, + 10 and the steel plate adherend rubber Results peel strength (KN / m)> 10> 10 PTFE plate with rubber peel strength (KN / m)> 7> 7 GQF-C-type bridge expansion GQF-C-type bridge expansion is to adapt one of highway bridge construction new types of bridge expansion joint device. GQF-C-type bridge expansion with the overall hot-rolled special steel 16Mn overcome extrusion profiled steel straightness and collection size characteristic uneven joints, GQF-C-type bridge expansion comprehensive technical performance and technical indicators have reached or exceeded the international advanced level Modular expansion joints, structural type and shaped steel rolling are a national initiative, will become the transportation industry standard recommended products GQF-C-type bridge expansion Features: Construction low height single slit expansion joints, the overall shape of the domestic hot-rolled shaped steel height of only 50mm, simple structure, easy installation Simple expansion joints, with significant reliability, comfort and durability suitable for deck pavement layer thickness equal or greater than 80mm, stretching the amount of 80mm or less all kinds of bridges, which is convenient to replace the old bridge expansion, but also for the construction of a new bridge selection GQF-C-type bridge expansion rubber seal in the middle of its technical requirements: the use of neoprene ( CR) with a telescopic device is suitable for the temperature of the sealing rubber band -25 ℃ - + 60 ℃ areas with natural rubber (NR) seal the rubber band [1] device is suitable for a temperature of -40 ℃ -.. + 60 ℃ area bridge expansion sewn rubber seal | quality and quantity | joints provided by Hengshui Gallop Gallop Road and Bridge Engineering Co., Ltd.
